Specication forming part of Letters Patent No. 143,828, dated October21, 1.873 application filed July 5, 1873.

To all whom t may concern:

Be it known that I, RICHARD LLOYD, of Cleveland, in the county ofCuyahoga and State of Ohio, have invented a new and useful Improvementin Car- Coupling, of which the following is a specication:

Figure lis a side view of my improved coupling. Fig. 2 is a top view ofthe same. Fig. 3 represents a plate` for receiving the point of theopposite coupling-bar.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved car-coupling,which shall be simple in construction, and safe, reliab1e, andconvenient in use, being so constructed as to couple automatically asthe cars are rim together, and which may be uncoupled from the platformor top of the car, as may be required. The ini-*ention consists in theconpling-bars, provided with V-shaped and. inclined or dovetailedshoulders upon their upper and lower sides, and .at different distancesfrom their points, and jointed to the ends of the draw-bars, ashereinafter fully described.

A represents lthe draw-bars of two adjacent cars, to the ends of whichare jointed the ends of the coupling-bars B, which joints are so formedthat the bars B cannot drop much below a horizontal position, but may beturned up for uncoupling the cars. Upon the upper and lower sides ofeach of the bars B are formed shoulders b', which are made V-shaped andinclined or dovetailed, as shown in Figs. 1 and 2. The V shape of theshoulders b prevents them from slipping from each other in passingaround curves, and the dovetail of said shoulders prevents the bars Bfrom jarring or jumping away from each other as the cars are runtogether, or when the train is under way. The shoulders b of eachcoupling-bar B are formed, the one in advance of the other, as shown inFig. 1. VThe bars B are inclined upon their upper and lower sides, sothat they may slide up upon each other, as the cars are run together andinterlock with each other. In the-forward parts ofthe bars B are formedholes to receive an ordinary coupling-pin, to enable a car provided withmy improved coupling to be coupled with a car provided with an ordinarylink-coupling. To the side of the forward parts of the bars B areattached chains C, which extend up to the platform or top of the car, sothat the upper bar may be raised to nnconple the cars from the saidplatform or top, as may be desired or convenient.

By this construction cars of the same height and of diiferent heightsmay be coupled as they are run together with the same convenience.

D is a plate, designed to be attached to the forward end ofthe cars, toreceive the point of the opposite bar B, as the cars are run together.

Having thus described my invention, I cl aim as new and desire tor`secure by Letters PatentrEhe coupling bars B, provided with V- shapedand inclined or dovetailed shoulders b upon their upper and lower sides,and at dii'erent distances from the points of said bars, and jointed tothe ends of the draw-bars A, substantially as herein shown anddescribed.

RICHARD LLOYD.
